The gravitational constant (G) is a fundamental constant in physics that describes the strength of the gravitational force between two objects. It has a value of approximately 6.67430(15) x 10-11Newtons (m2/kg2). Gravity and Everyday Objects ...
The gravity acceleration formula can be used in the usual way with the so-called Newtonian equations of motion that relate mass (m), velocity (v), linear position (x), vertical position (y), acceleration (a) and time (t) . That is, just a...
Weightis the amount offorcewith which Earth'sgravitypulls on a particular mass: the more massive something is, the more gravitational force, and the more we say it weighs. Like any other force, we should measure weight in newtons. If you're a person with a mass of 80kg, Earth's gravi...
How much salt is in the average human body? Suppose a solid substance has a specific gravity of 8.0. a) How much would 3.0 cmsup3 of the solid substance weigh in air? b) Would it weigh the same/less/more when completely immersed in water? c) What would it weigh when completely immer...
If anyone asked our weight why would we say only in Kg's but not in newtons? A 5 kg mass was lifted 365 cm, how much work was done against gravity? What is the conversion factor used for converting the unit Newton-seconds (Ns) to kilogram-meter per second-squared over seconds (kgM...
How much work is done when 100 kg lifted 5 meters above the ground?How much work is needed to lift a 3-kg mass a distance of 0.75 m?How much work is done against gravity in lifting a 6.5-kg weight through a distance of 21 cm?
gravity, tension is 52 kilonewtons. With SF=6, the mass of a 150-meter Spectra or Dyneema tape is less than 30 kilograms. If sized just for Moon gravity, it is less than 13 kilograms. Support hardware may add 10 to 20 kilograms. Tests using an inflatable volume and its attach ...
Potential energy is energy objects have stored either by virtue of gravity or of their elasticity. Kinetic energy is energy objects have by being in motion. Let's number the balls one through five. When all five are at rest, each has zero potential energy because they cannot move down any...
I have heard a lot about how gravity is the weakest force and after thinking about it for a while, I don't really see why it is. One argument I heard for gravity being the weakest is how the value for G in F=G*m*m/r^2 is so much lower than the value of k in F=k*q*q...
TheNewton's Gravity Puzzleis a very simple puzzle. The objective is to remove the center piece while keeping the puzzle on a level surface. No tools can be used to remove it, only your body and the puzzle itself. Here are the steps to make your own puzzle along with the solution at ...
